Polygonization

polygonization

[pə‚lig·ə·nə′zā·shən]

(solid-state physics)

A phenomenon observed during the annealing of plastically bent crystals in which the edge dislocations created by cold working organize themselves vertically above each other so that polygonal domains are formed.

Polygonization

the second stage in the return of metals. Upon heating after large deformations, polygonization is, as a rule, an initial stage in recrystallization of metals.

Apart from the grain boundaries, where several dislocations pile up after having moved through the core grain along preferential crystal slip planes, the problem of the line defects deserves a simulation model that extends some relevant concepts of the dislocation science: are known in solid state physics phenomena like dislocation climb and jog, polygonization structures and so on.
